Answer

Choice B.

Work Step by Step

The energy starts out at zero when the particles are very far apart. As the negatively-charged electron and positively-charged proton are brought closer, the energy of the pair decreases and becomes negative. The quantized energy levels cannot take on arbitrary values. As discussed on page 791, the lowest energy state has an energy of -13.6 eV.
